To mark National Catalan day on Wednesday, Catalan separatists
will attempt a 250 mile human chain along the coastline of the
Catalonia region, in north-east Spain. This demonstration is part of the
continued bid for a referendum for independence from Spain, which is
strongly opposed by the Spanish government.

If you're planning to take part, or know people who are, we'd like to see your pictures and videos. We're interested in the preparations for the event as well as the human chain itself. We will publish the best pictures and videos on the site. Here's a gallery of your best pictures so far.
